Good luck to both of you. Pauly, besides form it may be useful to post what kind of training you've done over the last few years. Basically a sort of overview of you typcial routine. I mean, there could be some obvious problems. For instance a whole lot of benching a little else
ZXNV it sounds like you need a shoulder overhaul (I mean a "repair" program not the assinine big shoulder Thib routine by the same name). Especially given what you said about the scapula. I would suggest that you limit overhead pressing and just drop the inclines altogether. If you do OHP then use dumbells and do it in the "scapular plane". Basically that is what people mean when they say "to the front" So if pressing with your elbows extended out to the sides is zero degress, basically you press with the dumbells about 30 degrees in from there, toward the midline of your body. Trying light weights you may find doing it that way gives you less popping and grinding.
